Ah, you mean
In[3]:= Quantity["earth's gravity"]
Out[3]= Quantity[1, "StandardAccelerationOfGravity"]
then you can
In[9]:= QuantityForm[
Quantity[1, "StandardAccelerationOfGravity"], "LongForm"]
Out[9]//QuantityForm= StringForm["`1` `2`", 1, "standard acceleration \
due to gravity on the surface of the earth"]
In Quantity it reads
Supported units include all those specified by NIST Special
Publication 811.
And here it is
In[25]:= Take[
EntityValue["PhysicalConstant", {"Name", "Value"}], {187, 187}]
During evaluation of In[25]:= Quantity::unkunit: Unable to interpret unit specification EddingtonConstant4.
During evaluation of In[25]:= Quantity::unkunit: Unable to interpret unit specification ElectronProtonElectricGravitationalForceRatio.
During evaluation of In[25]:= Quantity::unkunit: Unable to interpret unit specification (SpeedOfLight)^2/(MONDConstant).
During evaluation of In[25]:= General::stop: Further output of Quantity::unkunit will be suppressed during this calculation.
Out[25]= {{"standard acceleration of gravity",
Quantity[196133/20000, ("Meters")/("Seconds")^2]}}
For the sake of diversity it has four different textual representations
- standard acceleration of gravity
- StandardAccelerationOfGravity
- standard acceleration due to gravity on the surface of the earth
- g
